What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
MAIN
conclusionMpMYB02, a regulator of marchantin accumulation, also acts as a key regulator of oil body formation. MpMYB02 induces the expression of MpSYP12B and promotes oil body formation, subsequently leading to marchantin accumulation. The oil body observed in Marchantia polymorpha is a cellular organelle surrounded by a unit membrane, accumulating various secondary metabolites such as marchantins and terpenes. We observed that oil body formation is regulated by MpMYB02, a key regulator of marchantin accumulation. In the Mpmyb02 mutant, no oil bodies were observed, although idioblast-like cells were present in the gemma. We introduced MpMYB02-glucocorticoid receptor (GR), a steroid-inducible transcriptional activator, into Mpmyb02 and assessed the effect of dexamethasone (DEX) on oil body formation. Following DEX treatment, transformed liverworts began forming oil bodies within 12 h. During the initial stages of oil body development, we observed the aggregation of small globular structures. DEX treatment upregulated several genes implicated in oil body formation, including MpSYP12B. Our findings underscore that MpMYB02 plays a crucial role not only in marchantin accumulation but also in oil body formation.
